Subject: Re: linux-next: build warning after merge of the pm tree
Hi, Stephen,
Sorry that I missed this build warning in the first place, thanks for
reporting.
The patch below fixes it.
BTW, Rafael, I think acpi_fpdt_init() also needs to be fixed to have
proper return value.
Do you prefer an incremental patch or a V2 of 208757d71098 ("ACPI:
tables: introduce support for FPDT table"), which includes all these
fixes?
thanks,
rui
